I know this is kind of big, but it's the only way to see the bird. I think, big think here, that this is an immature green heron. The general shape and beak size are right. I'm going to have to start carrying the the 35 mm with the longer lens if this keeps up. Spotted this one down at the park this morning. There were three moving through the trees and this one was kind enough to strike a pose. Lisa, have you seen anything that looks like this.
